Related issue: - https://github.com/gorhill/uBlock/issues/3212 The element picker will now properly work on sites where cosmetic filtering is disabled, but will not allow the creation of cosmetic filters when specific cosmetic filters are not meant to be enforced in the current page. When specific cosmetic filters are not meant to be enforced, the element picker will still allow the creation of network filters, that is unless the current page is trusted, in which case using the element picker is pointless.
